What does 'lspci -v' say for your machine?
Sorry, i'me not too familiar with the USB architecture. Anyway here is the relevant lspci entries (note: I did this under my working 2.4.18)
02:08.0 USB Controller: NEC Corporation USB (rev 41) (prog-if 10 [OHCI]) Subsystem: Unknown device 807d:0035 Flags: bus master, medium devsel, latency 32, IRQ 19 Memory at cd000000 (32-bit, non-prefetchable) [size=4K] Capabilities: [40] Power Management version 2
02:08.1 USB Controller: NEC Corporation USB (rev 41) (prog-if 10 [OHCI]) Subsystem: Unknown device 807d:0035 Flags: bus master, medium devsel, latency 32, IRQ 16 Memory at cc800000 (32-bit, non-prefetchable) [size=4K] Capabilities: [40] Power Management version 2
02:08.2 USB Controller: NEC Corporation USB 2.0 (rev 02) (prog-if 20 [EHCI]) Subsystem: Unknown device 807d:1043 Flags: bus master, medium devsel, latency 32, IRQ 17 Memory at cc000000 (32-bit, non-prefetchable) [size=256] Capabilities: [40] Power Management version 2

Not too good beacuse I don't have the option of enabling OHCI :) Are we still keeping it?
